4468c569f7 domain_codec: optimize dname_dec and convert_dname 
dname_dec: now iterates over the packet only once.
convert_dname: remove redundant checks and code shrink.

While testing I've noticed that some of the tests didn't compile
properly, so I fixed them.

function                                             old     new   delta
dname_dec                                            286     267     -19
dname_enc                                            166     143     -23

0ef64bdb40 *: make GNU licensing statement forms more regular 
This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).
